We just got a heads up that the 2D Demo in PUN v1.62 has a Missing Script issue.The script that's missing is "OnJoinedInstantiate", which is a component that instantiates prefabs on join. In this case, it should instantiate the "Robot Kyle 2D" prefab from the package.

We will fix this in the next update. Meanwhile, have a look at this component screenshot, to fix things yourself.
